Who is allowed to deposit items What type of items will they deposit Who else needs to review, enhance, or approve the submission To what collections can they deposit material Who can see the items once deposited All of these issues are addressed by the Community representatives, working together with the Libraries DSpace user support staff, and are then modeled in a workflow for each collection to enforce their decisions.As their constituents produce increasing amounts of original material in digital formatsmuch of which is never published by traditional meansthe repository becomes vital to protect the significant assets of the institution and its faculty.The first part of this article describes the DSpace system including its functionality and design, and its approach to various problems in digital library and archives design.The second part discusses the implementation of DSpace at MIT, plans for federating the system, and issues of sustainability.
HP Labs and MIT Libraries released the system worldwide on November 4, 2002, under the terms of the BSD open source license 1, one month after its introduction as a new service of the MIT Libraries. As an open source system, DSpace is now freely available to other institutions to run as-is, or to modify and extend as they require to meet local needs. From the outset, HP and MIT designed the system to be run by institutions other than MIT, and to support federation among its adopters, in both the technical and the social sense. As faculty and other researchers develop research materials and scholarly publications in increasingly complex digital formats, there is a need to collect, preserve, index and distribute them: a time-consuming and expensive chore for individual faculty and their departments, labs, and centers to manage themselves. The DSpace system provides a way to manage these research materials and publications in a professionally maintained repository to give them greater visibility and accessibility over time. The project focus was on building a production quality system. It complements and was influenced by previous research in computer science and digital library architectures 2. Our goals were to build a system that: would be immediately useful at MIT, and hopefully at other institutions; could be expanded and improved over time; and could serve as a platform for future research. Dspace Help How To Best SupportWith the help of developers at other institutions that adopt DSpace under its open source license, we will work to add features and improve the different functions of the system as we learn what users actually want, and how to best support such complex requirements as digital preservation and digital rights management. The systems information model is built around the idea of organizational Communitiesnatural sub-units of an institution that have distinctive information management needs. In the case of MIT (a large research university) Communities are defined to be the schools, departments, labs, and centers of the Institute. Each Community can adapt the system to meet its particular needs and manage the submission process itself. Only three fields are required: title, language, and submission date, all other fields are optional. There are additional fields for document abstracts, keywords, technical metadata and rights metadata, among others. This metadata is displayed in the item record in DSpace, and is indexed for browsing and searching the system (within a collection, across collections, or across Communities). For the Dissemination Information Packages (DIPs) of the OAIS framework, the system currently exports metadata and digital material in a custom XML schema while we work with the METS 3 community to develop the necessary extension schemas for the technical and rights metadata about arbitrary digital formats. There are several interfaces: one for submitters and others involved in the submission process, one for end-users looking for information, and one for system administrators. Once an item is located in the system, retrieval is accomplished by clicking a link that causes the archived material to be downloaded to the users web browser. Web-native formats (those which will display directly in a web browser or with a plug-in) can be viewed immediately; others must be saved to the users local computer and viewed with a separate program that can interpret the file (e.g., a Microsoft Excel spreadsheet, an SAS dataset, or a CADCAM file). In other words, different DSpace Communities, representing different schools, departments, research labs and centers, have very different ideas of how material should be submitted to DSpace, by whom, and with what restrictions.
